How the count works

A week is seven calendar days, so 20 weeks is 140 days, weekends and holidays included. Today is the starting point and isn’t counted, which is why the answer always falls on the same day of the week as today. The calculator reads the date on your device, so the start is your today, not the server’s.

What people count 20 weeks for

• Halfway through a pregnancy. A full-term pregnancy is counted as 40 weeks from the last period, so 20 weeks is the midpoint, and the anatomy scan is usually done between 18 and 22 weeks. Your provider schedules it; the due date calculator shows your week.
• Long training plans. A first marathon plan for someone starting from scratch, or a half-Ironman plan, often runs about 20 weeks.
• Four and a half months, roughly. 140 days is four months and about two and a half weeks, depending on which months it crosses. Five calendar months from today would be Tuesday, March 30, 2027.
